We analyze from the perspective of complex networks the properties of seven community trophic webs (defining who eats whom in an ecosystem) from a variety of environments. Remarkably, we find simple robust patterns that describe the properties of the trophic webs considered. Our results also suggest that the structure of the food webs studied may be approximated, to first order, by a random graph with specific distributions of number of incoming and number of outgoing (trophic) links. Moreover, our results are consistent with the possibility that several quantities characterizing a food web depend on a single parameter.
